同步带是以钢丝绳或玻璃纤维为强力层，外覆以聚氨酯或氯丁橡胶的环形带，带的内周制成齿状，使其与齿形带轮啮合。同步带传动时，传动比准确，对轴作用力小，结构紧凑，耐油，耐磨性好，抗老化性能好，一般使用温度-2080，v50m/s，P300kw,i10,对于要求同步的传动也可用于低速传动。同步带传动具有以下特点：（1）传动准确，工作时无滑动，具有恒定的传动比；（2）传动平稳，具有缓冲、减振能力，噪声低；（3）传动效率高，可达0.98，节能效果明显；（4）维护保养方便，不需润滑，维护费用低；（5）速比范围大，一般可达10，线速度可达50m/s，具有较大的功率传递范围，可达几瓦到几百千瓦；（6）可用于长距离传动，中心距可达10m以上。工业同步带的型号：“T”型齿工业用同步带型号 节距 (mm) 齿高 (mm) 带厚 (mm) 角度 MXL 2.032 0.51 1.14 40 XL 5.080 1.27 2.30 50 L 9.525 1.91 3.60 40 H 12.70 2.29 4.30 40 XH 22.225 6.35 11.20 40 XXH 31.750 9.53 15.70 40 T2.5 2.5 0.7 1.30 40 T5 5 1.20 2.20 40 T10 10 2.50 4.50 40 T20 20 5.00 8.00 40 AT5 5 1.20 2.70 50 AT10 10 2.50 5.00 50 AT20 20 5.00 8.00 50 圆弧齿工业用同步带齿型代号 型号 节距 (mm) 齿高 (mm) 带厚 (mm) HTD 2M 2 0.75 1.36 3M 3 1.17 2.4 5M 5 2.06 3.8 8M 8 3.36 6.00 14M 14 6.02 10.00 20M 20 8.4 13.20 STPD/STS S2M 2 0.76 1.36 S3M 3 1.14 1.9 S4.5M 4.5 1.71 2.81 S5M 5 1.91 3.4 S8M 8 3.05 5.3 S14M 14 5.3 10.2 RPP/HPPD 2M 2 0.76 1.36 3M 3 1.15 1.9 5M 5 1.95 3.5 8M 8 3.2 5.5 14M 14 6.00 10项目梯形齿圆弧齿XLLHXHXXH3M5M8M14M20M拉伸强度 N/mm8012027038045090160300400520参考力伸长率参考力 N609022030036070130240320410伸长率 %4.0硬 度755包布粘合强度 N/mm56.581012-6101215芯绳粘合强度 N/mm2003806008001500-40070012001600齿体剪切强度 N/mm5060707590-506080100齿轮直边齿形尺寸和公差(mm)节线代号bwhg+1.5rbrt2查 看MXL0.840.050.69200.350.130.508详细规格XXL1.140.050.84250.350.300.508详细规格XL1.320.051.65250.410.640.508详细规格L3.050.102.67201.191.170.762详细规格H4.190.133.05201.601.61.372详细规格XH7.900.157.14201.982.392.794详细规格XXH12.170.1810.31203.963.183.048详细规格MXL-最轻型；XXL-超轻型；XL-特轻型；L-轻型；H-重型；XH-特重型；XXH-超重型。同步带的标记为：带长代号 带型 带宽代号。MXL型同步带轮尺寸表单位：(mm)规格齿数节径 d外径 do档边直径 df档边内径 db档边厚度 h22MXL2214.2313.721812123MXL2314.8814.371812124MXL2415.5215.021812125MXL2516.1715.661812126MXL2616.8216.312211127MXL2717.4616.962211128MXL2818.1117.602211129MXL2918.7618.252211130MXL3019.4018.902211132MXL3220.7020.192515134MXL3421.9921.482515136MXL3623.2922.782617138MXL3824.5824.072918140MXL4025.8725.362918142MXL4227.1726.662918144MXL4428.4627.953221146MXL4629.7529.253221148MXL4831.0530.5434.524.5150MXL5032.3431.8334.524.5152MXL5233.6333.1337.828160MXL6038.8138.304432172MXL7246.5746.0651361XL型同步带轮尺寸表单位：(mm)规格齿数节径 d外径 do档边直径 df档边内径 db档边厚度 h10XL1016.1715.662211111XL1117.7917.282211112XL1219.4018.902515113XL1321.0220.512515114XL1422.6422.132617115XL1524.2623.752918116XL1625.8725.362918117XL1727.4926.983221118XL1829.1128.603221119XL1930.7230.2234.524.5120XL2032.3431.8337.828121XL2133.9633.454027122XL2235.5735.074027123XL2337.1936.684027124XL2438.8138.304432125XL2540.4339.924432126XL2642.0441.434929127XL2743.6643.154838128XL2845.2844.774838130XL3048.5148.005136132XL3251.7451.2458471.534XL3454.9754.4758471.536XL3658.2157.7061451.538XL3861.4560.9464481.540XL4064.6864.1768521.542XL4267.9167.4173611.544XL4471.1570.6478661.546XL4674.3873.8778661.548XL4877.6277.1182641.550XL5080.8580.3486701.560XL6097.0296.51102701.572XL72116.43115.921211091.5L型同步带轮尺寸表单位：(mm)规格齿数节径 d外径 do 档边直径 df档边内径 db 档边厚度 h12L1236.3835.624027113L1339.4138.654432114L1442.4541.684929115L1545.4844.725136116L1648.5147.755439117L1751.5450.7861451.518L1854.5753.8161451.519L1957.6156.8461451.520L2060.6459.8864481.521L2163.6762.9168521.522L2266.7065.9475551.523L2369.7368.9775551.524L2472.7772.0080601.525L2575.8075.0482641.526L2678.8378.0786701.527L2781.86
